N ON REFILLAB LE BOTTLE Application filed August 28, 1907.

Specification of Letters Patent.

Patented July 28, 1908.

Serial No. 390,563.

To all whom it may concern:

Be it known that I, HERBERT L. MITCHELL, citizen of the United States, residing at Stoneville, in the county of Rockingham and State of North Carolina, have invented certain new and useful Improvements in N on- Refillable Bottles, of which the following is a specification.

The present invention relates to certain new and useful improvements in bottles of that type which are provided with a valve mechanism to prevent any liquid from being forced into the interior thereof after the initial filling, thereby rendering it impossible for dealers in bottled goods to substitute material of an inferior nature for the original contents of the bottle after the latter has been removed.

The primary object of the'invention is to design a bottle of this character which is of simple and inexpensive construction and operates in an effective manner to produce the above mentloned result.

' For a full understanding of the lnventlon and the merits thereof and also to acquire a knowledge of the details of construction and the means for efiecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a vertical sectional view through a bottle embodying the invention,v

the said bottle being shown in an upright position. Fig. 2 IS a similar view showing the bottle as turned upon one of its sides.

' Fig. 3 is also a similar view showing the bottle in an inverted position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The invention may be applied to a necked receptacle or bottle of any suitable configuration of which the numeral 1 designates the body portion and 2 the neck. Projecting inwardly within the neck 2 at. an intermediate point in the length thereof is an annular rib 3 which serves as a support for the valve 4. In the present instance this valve 4 is in the nature of a disk fitting closely within the'bottle neck so as to render it impossible to tamper with the valve or lift it from its seat without injuring the same and clearly indicating such tampering. For the purpose of enabling a tight closure to be obtained for the bottle a washer 5 of rubber or similar material is placed upon the rib 3 so as to engage the valve 4 when the bottle is in an upright position. An annular flange 6 is arranged immediately below the rib 3 and projects inwardly and downwardly so as to have approximately the form of an inverted cone, an opening being provided at the apex thereof.

Pendent from the valve 4 is a chain or flexible member 7 which passes through the opening at the apex of the conical flange 6 and has a weight 8 applied to the extremity thereof. This weight 8 may be of any suitable material such as metal or glass and has an elongatedformation which permits it to pass through the opening at the apex of the conical flange 6 when turned longitudinally with respect to the same. It will be observed however that the flexible member 7 is attached to the weight 8 at an intermediate point in the length thereof so that the weight is normally disposed transversely with respect to the before mentioned opening and engages the flange 6 insuch a manner as to prevent the weight from being drawn back through the opening after being inserted through the same. The weight 8 and valve 4 are of approximately the same weight and tend to counter balance each other when the bottle is turned upon its side as indicated in Fig. 2. The pressure of the liquid within the bottle bearing against the valve 4 operates to unseat the said valve and permit the-liquid contents of the bottle to be poured out of the same when the bottle is turned into the position shown in Fig. 2. Attention is directed to the fact that the weight 8 normally operates to hold the valve closely upon its seat, but that when the bottle is turned from an upright position the said weight falls against the flange 6 and retains the valve in a position adjacent the washer 5. From theforegoing description it will be readily apparent that my improved valve mechanism will operate in an effective manner to prevent any liquid from being poured into the interior of the bottle after the original contents thereof has been removed.

Having thus described the invention, what is claimed as new is:

In a device of the character described, the combination of a necked receptacle, an annular rib projecting within the neck thereof, an inverted conical flange projecting inwardly and downwardly within the neck below the'before mentioned annular rib and having an opening at the apex thereof, a

disk valve fitting loosely within the neck and I of the valve and the flexible cord permitting normally resting upon the annular rib, a l the weight to swing to one side into engagefiexible cord pendent from the disk valve ment with the inverted conical flange when and extending through the o ening at the the bottle is tilted. 15 a ex of the inverted conical flange, and an I In testimony whereof I affix my signature efonlgatgld vielight alppligd E10 theZ1 extrkemity in presence of two witnesses.
